SDK to Build Pilot Plant for Heat-Resistant, Transparent Film


Showa Denko K.K. (SDK) has decided to build a pilot plant at its Oita Complex to produce heat-resistant and transparent film for use in displays.  After start-up of the pilot plant scheduled for June 2011, SDK will provide samples that satisfy respective customers’ requirements, accelerating marketing activities in preparation for the launch of the business on a full scale.

SDK has developed raw material resin for the film based on its proprietary resin technology for glass lens applications.  The film will have high transparency, and high heat resistance required at the time of display production.  Major characteristics of the film are as follows:

Heat resistance: Can be used in high-temperature processes of up to 250°C
Optical characteristics: High light transmittance of 92% (comparable to that of glass);Low double refraction
Chemical resistance: High resistance to acids, alkalis, and organic solvents
Surface characteristics: High surface hardness of 3H or more (in pencil hardness)

The pilot plant will have the capacity to produce several hundred-thousand square meters of the film a year in the form of rolls and sheets.

By deepening its resin technologies in terms of molecular design and molding/processing, SDK will expand its film operations to cover not only the field of displays (touch screens, LCDs) but also optical films that require high performance.  SDK will aim to achieve annual sales of \20 billion from overall film operations by 2020.
